An electromagnetic variable-ratio torque convertor

The torque convertor differs radically from any other type known to be in commercial use. It depends for its operation upon the phenomenon exemplified in Faraday´s disc and constitutes, theoretically, an `infinitely variable¿ gear whose ratio can be varied over a wide range. This paper is limited to a brief description of the basic principles and some details of the experimental results obtained from tests on a simple model.
